The information within ORegAnno is regularly mapped and provided as a [http://genome.ucsc.edu/cgi-bin/hgTrackUi?org=Human&g=oreganno UCSC Genome Browser] track.  Furthermore, each entry is associated with its experimental evidence, embedded as an [http://www.oreganno.org/oregano/evidenceview.action Evidence Ontology] within ORegAnno.  This allows the researcher to analyze regulatory data using their own conditions as to the suitability of the supporting evidence.
